چکیده
The T helper type 2 (TH2) locus control region is important in the regulation of the genes encoding the cytokines interleukins 4, 5 and 13. Using the chromosome conformation capture technique, we found that in T cells, natural killer cells, B cells and fibroblasts, the promoters for the genes encoding TH2 cytokines are located in close spatial proximity, forming an initial chromatin core configuration. In CD4+ T cells and natural killer cells, but not B cells and fibroblasts, the TH2 locus control region participates in this configuration. The transcription factors GATA3 and STAT6 are essential for the establishment and/or maintenance of these interactions. Intrachromosomal interactions in the TH2 cytokine locus may form the basis for the coordinated transcriptional regulation of cytokine-encoding genes by the TH2 locus control region.

متن کاملSelf-consistent Spectral Function for Non-Degenerate Coulomb Systems and Analytic Scaling Behaviour
Novel results for the self-consistent single-particle spectral function and self-energy are presented for non-degenerate one-component Coulomb systems at various densities and temperatures. The GW (0)-method for the dynamical self-energy is used to include many-particle correlations beyond the quasi-particle approximation. The self-energy is analysed over a broad range of densities and temperat...
